802.15.4a/ab/ac, seems even weirder, given what we’ve become used to with AM/FM signaling modes.
After the usual “Huh, that seems like a clever way to send signals” reaction, a closer perusal of the tech & its established industrial capabilities, reveals Surface penetrating radar for machine vision & medical imaging, P2P, P2MP, local file-exchange, low-power low-latency streaming, greater range than bluetooth, greater interference resistance than WiFi, & reduced airtime per Mb, at lower emission power than a hair dryer or cellphone.
Gee, I wonder why it got forcibly channeled into exclusively device-to-device location pings, with no direct radio access or firmware, available to devs?
Seriously, go look at what the military, industrial, security, & medical sectors have already been doing with UWB, then look at the specs for the compact chipsets & SOCs released since 2017, & then look at what BMW, Apple, Google, & Samsung are doing with it. Oh yay, Airtags. I mean, they do work, but they’re about 1/1000th of what the U1 could do, if app devs had access to the radio instead of being gatekept behind the FindMy device-to-device services.
